F1 rures 1 to S show the wmdmur mechan-v GEORG LIECKFELD, subjects `of the German Emperor, residingat Hanover', Province of Hanover, Germany, have invented new and useful- Improvements in Winding Mechanism, of whlch the following is a full, clear, and

, exact description.

, Thepresent invention relates to windin `lr mechanisms such as aref so1neti1nes employed `-The invention comprises the detailsof construction hereinafter set forth, and particularly pointed out in the claims'.

In order to render .the present s 'ecification easily intelligible, reference is ha( to the acompanying drawings, 4in which similar letparts throughi ism, Pig. 1 being a part sectional elevation of the feed device for the strip to be wound;

l- Fig. v2, a'longitudinal section through the femlingecheeks and the cutter mechanism; Fig. 2, a cross-section through F ig. 2 F ig'. 3, a similar sec-.tional elevation'to that of Fig. 2, showing the f eed-checksin their rearward position Fig. 4, alongitudinal section through the shaft-'bcarings, showing` the lshaft on which thel parts oi' the box are wound;-Fig..5, a similar elevation in ',part, showingthe clamping device for the strip 1n operative p0' sition; Fig. a part sectional elevation show- `ing in section the mechanism for operatingv the ciampi11g-linger, Fig. 7, a planof Fig. Fig. 8, an end 'clevatlcm of the clamping-i1n rolled up to the desired degree, and automat ically pushed olf the end of the shaft. The feed-cheeks 7 and S, the latterof which is provided with ribs 18, which lie on'the ad' hesive side of the strip, are moved backward and forward 1n suitab e guldes by meansof a lever 10, plvotally connected. to a rock-lever 9 operatcd by a cam-'disk 13 and held against the same by aspringl. i

As will vbe seen from Fig. 2., the top cheek 8 is pressed onto the strip 1 `by alight spring,

i K, i A which as soon asl the end Be it known `that we, FRANZFETTBAGK and mg-- inger 14, 1s operated by means of a s ring 40. The rod 25 I of the strip fed has been' held `by a clampingffngerv hereinafter described, will allow the'ch'eeksto slide back over the strip withoutfpulling it back. The

'cutter 11, Figs. 1l to 3, is verticallyvreciprocated by means of a rock-lever 12,"having its roll held against the cam. 13 by means of a spring)17l. Thisroll is operated to' cutoff, the

strip y'means of 'a cam-surface15, ying in a different'vertical plane-to .that of the camsurface for the lever 9.l Thus when the-.strip has been sufficiently wound onto the end of 'Patented March eo,-`19o6. 55

theshaft it is 'automatically cut off.' rlfhe .Y

elamfpmgfnger 14, which retains the vendof 'the strip 1, is illustrated in Figs.' 4 toj.' Itis rigidly connected to a short'lever-1'9, pivoted vto a sleeve 21,' adapted to slide on a sleeve 20 i ofthe shaft 6, but

eyed to the same, so as to Irotate with, it. .A nose 19 of the said 'lever 19 extends down into 4a groove 29 of the shaft 6, and when this nose on the movement to' the left of Fig. .4 strikes the end of the vgroove 29 the sald lever 19 is turned on its pivot against the action of a spring and forces the finger 14 down onto the end of. the shaft, thus clamping the end. of the strip to thel said shaft and causing the same to be taken round when the shaft rotates. The sleeve 21,I carryinor the operating mechanism for the clampi? of a ring 24, loosely mounted thereon and pivotally connected tol the bifurcated end of a rod 25,

having a roll 26 ada ted to be operated by a rotary cam-disk 27, diiiven by suitable means. The shaft 6 is keyed to a sleeve 20, but is capable of axial movement therein, the said sleeve being mounted tolrotate in bearin s 22 and 23, 4but not being capable of longiturgiinal movement therein. The sleevey 20 carries the driving-pulley 30, loosely mounted thereon, and ia coupling-half 31 fast thereon, so that when the two` parts' 30 and 31 'are "engagement the shaft 6 and sleeve 2() willi erotated. The coupling-half 30 is operatedl'bya ring 32, loosely mounted thereon and in connection with'the fork of a rod 31, having a roll 34, held against a cam-disk y35 by moans is held againstj'lis camisk 27 by means of a s ring28. When the projections on the camisk 35 throwthe rod 33 .over to kthe vright of Fig. ling will be engaged and `the shaft and sleeve 2O will be rotated. When sucient material has been wound onto the end of the 4, thecoup? IOC fall, down into any; suitable receptacle.

shaft 6, the latter is pulled hack to the right of Fig. 7, and the end of the sleeve 20, which does not follow this ino vement, will push the roll. oil` the end. of the shaft, so that it may Previous to this operation the cutter, which is so timed, has severed the strip. The axial movement of the shalt is produced by' the .ring 365, coupled to the end of the shaft and also to the fork of' a rod. 37, l'iavingl a. roll 3S, :doh is held against a cam-disk 39 by means of a spring 4&1. 1lf3/Then the Cain of this disk comes round, it pushes the .rod 37 to the right, Fig. 7, and p ulls the shaft 6 along in the saine direction, so that the roll will heplished ofl the end of the said shaft 6. The shaft 6 is then again advanced, and the clampingcheeks are timed to advance the end of the strip-at this moment, sowthat as the sleeve 131 is infoved forward the linge le will clamp the advanced end of the strip :"or the next op# eration.

We claim as our inventionl, in a Winding meel'lanisni. for box-inakf' or other machines the combination of a rotary shaft on the end of whieh the material is Wound, a pair of reoiprooatory feed-cheeks to advance the' end of the strip of material over the end of the shaft, a sleeve in which said shaft is axiallj,T movable and having a linger pivoted therein, a nose extendinpr from said finger, a groove in the shaft in whieh said nose lies, a spring to normally hold the said finger up Ofi the shaft end, the said groove, bein@ so located that its end forces the linger down 011 the shaft When the sleeve. is advanced thereon substantially as described.

2. ln a mechanism of the class specified, the combination oll means for advancing the strip of material a step toward and over the end ol.i the rotary shaft, a pivo'ted linger adapted to clamp the said material end to the end of the shaft a sleeve longitudinally Inovahle on said shaft to careyv said linger and means in connection with said finger to move it down onto the strip end when the said sleeve moved along the shalt and llo retain it down until the windingoperation has heen `completed snhstantiall) described.

ln witness whereof we have hereunto set our hands in presence of two witnesses,
